val find : ('a -> bool) -> 'a BatLazyList.t -> 'a optionfind p l returns Some x where x is the first element of l such
that p x returns true or None if such element as not been found.
val rfind : ('a -> bool) -> 'a BatLazyList.t -> 'a optionrfind p l returns Some x where x is the last element of l such
that p x returns true or None if such element as not been found.
val findi : (int -> 'a -> bool) -> 'a BatLazyList.t -> (int * 'a) optionfindi p e l returns Some (i, ai) where ai and i are respectively the
first element of l and its index, such that p i ai is true,
or None if no such element has been found.
val rfindi : (int -> 'a -> bool) -> 'a BatLazyList.t -> (int * 'a) optionrfindi p e l returns Some (i, ai) where ai and i are respectively the
last element of l and its index, such that p i ai is true,
or None if no such element has been found.
val split_at : int ->
'a BatLazyList.t ->
[ `Invalid_index of int | `Ok of 'a BatLazyList.t * 'a BatLazyList.t ]Whenever n is inside of l size bounds, split_at n l returns
`Ok (l1,l2), where l1 contains the first n elements of l and l2
contains the others. Otherwise, returns `Invalid_index n
val at : 'a BatLazyList.t -> int -> [ `Invalid_index of int | `Ok of 'a ]If n is inside the bounds of l, at l n returns `Ok x, where
x is the n-th element of the list l. Otherwise, returns
`Invalid_index n.
val assoc : 'a -> ('a * 'b) BatLazyList.t -> 'b optionassoc a l returns Some b where b is the value associated with key a
in the list of pairs l. That is, assoc a [ ...; (a,b); ...] = Some b
if (a,b) is the leftmost binding of a in list l.
Return None if there is no value associated with a in the
list l.
val assq : 'a -> ('a * 'b) BatLazyList.t -> 'b optionAs BatLazyList.Exceptionless.assoc but with physical equality
